Design and Evaluation of an Interactive Simulated Reverberant Environment

There are many existing approaches to the challenge of simulating a reverberant field. Most of these methods are designed to operate on a signal that has been recorded in a relatively anechoic environment and seek to add in simulated reverberation of a chosen space. This paper describes a low-cost, scalable approach for directly converting an acoustically dry space into a reverberant space of a larger size, with a number of configurable parameters. This is accomplished by harnessing the mutual feedback among microphones and loudspeakers arranged in the space. The result is a simple, tunable, and interactive system for creating a convincing reverberant environment. Several novel applications of such a system are also discussed.
